Where do our data come from?

Learn about the process of photon detection and reconstruction in Positron Emission Tomography (PET) imaging. Explore the use of photon-catcher's mitt, opposing detector banks, and CTI HR detector modules for detecting emitted photon pairs. Discover how to create time-activity curves for different regions of interest.

  1. Where do our data come from? Positron Emission Tomography (PET)

  2. A quick introduction to dynamicPET Photons!

  3. How to catch some photons? Use a photon-catcher’s mitt …or two

  4. Reconstruct caught photons…

  5. Opposing detector banks detect “coincidences” - emitted photon pairs CTI HR detector modules fov = 23 cm Pb shielding (front and rear) Photon Catcher - Small Animal Scanner Hutchins, G & Rouze, N Spatial Resolution: 2.5 mm FWHM at center of FOV Rouze NC, Hutchins GD. Design and Characterization of IndyPET-II: A High Resolution, High Sensitivity Dedicated Research Scanner. IEEE Transaction on Nuclear Science, 2003. 50(5): p. 1491-1497

  6. Image over time…

  7. Create time-activity curves for each region of interest
